So the Steam Sega collection has rolled out Workshop support. Workshop, usually offered with games that either have a comprehensive level editor, or some kind of modding community, tends to make most games more valuable to own. But what on earth could a user get from a workshop in this case? Rom Hacks. If you own any of the Sega Genesis/Mega Drive games on Steam, you can get one-click, no patch required rom hacks.
I took a look at the catalog this morning and some of the games offered at this point are translations of Japanese versions such as Bare Knuckle III, but more interesting are the straight up bootleg games that are offered. I saw one workshop item for a Mario clone built off of Wonder Boy III. It's a bold move by Sega and it's nice to see the users get a little something extra.
